Intelligent power switch with active di/dt control for automotive motor driver

International Rectifier has introduced the AUIR3330S Intelligent Power Switch (IPS) with a proprietary active di/dt control feature to reduce conducted EMI and switching in automotive motor drive applications.

The new 40 V high-side device packs bootstrap regulator, charge pump and high-side driver into a single device. The load can be driven up to 40 kHz at 100 percent of duty cycle. The other features of AUIR3330S include programmable over-current and over-temperature protection required by applications operating in harsh automotive environments such as pumps and fans. The AUIR3330S also features current sensing feedback, a diagnostic function, very low current consumption in sleep mode and ESD protection.

"IR's innovative active di/dt control drastically reduces conducted EMI on the input supply without increasing switching losses, enabling a reduction in the size of the EMI filter and the heat sink for more efficient compact motor systems," said David Jacquinod, product marketing manager, IR's Automotive Products Business Unit.

The device is qualified according to AEC-Q100 standards and is RoHS compliant.
